Limited Assurance Report of the Independent Auditor regarding Sustainability Information1

To the Management Board of METRO AG, Düsseldorf

We have performed an independent limited assurance engagement on the sustainability information published in the “Corporate Responsibility Report 2021/22” (further “Report”) for the period from October 1, 2021 to September 30, 2022 of METRO AG, Düsseldorf (further “Company”), published online at

It was not part of our engagement to review product- and service-related information, references to external websites and information sources, as well as future-related statements in the Report. As disclosed in the section ‘Social audits’, certifications on manufacturing facilities of suppliers were conducted by external certification firms mandated by METRO AG to ensure compliance with the environmental, social and health standards of the amfori Business Social Compliance Initiative (BSCI) or equivalent standards. The appropriateness and accuracy of the conclusions from the audit/certification work performed was not part of our assurance procedures.

Management’s Responsibility

The legal representatives of the Company are responsible for the preparation of the Report and the determination and presentation of the sustainability information in accordance with the Reporting Criteria. METRO AG applies the principles and standard disclosures of the Sustainability Reporting Standards of the Global Reporting Initiative (GRI), the Corporate Accounting and Reporting Standard (Scope 1 and 2) and the Corporate Value Chain (Scope 3) Standard of World Resources Institute / World Business Council for Sustainable Development, supported by internal guidelines (further: Reporting Criteria).

This responsibility of the legal representatives includes the selection and application of appropriate methods to prepare the Report and the use of assumptions and estimates for individual disclosures which are reasonable under the given circumstances. Furthermore, the legal representatives are responsible for the internal controls they deem necessary for the preparation of the Report that is free of – intended or unintended – material misstatements.

Practitioner’s Responsibility

It is our responsibility to express a conclusion on the Report based on our work performed within a limited assurance engagement.

We conducted our work in accordance with the International Standard on Assurance Engagements (ISAE) 3000 (Revised): “Assurance Engagements other than Audits or Reviews of Historical Financial Information” and the International Standard on Assurance Engagements (ISAE) 3410: “Assurance Engagements on Greenhouse Gas Statements” of the International Auditing and Assurance Standards Board (IAASB).

Accordingly, we have to plan and perform the assurance engagement in such a way that we obtain limited assurance as to whether any matters have come to our attention that cause us to believe that the Report of the Company for the period from October 1, 2021 to September 30, 2022 has not been prepared, in all material respects, in accordance with the Reporting Criteria. We do not, however, issue a separate conclusion for each disclosure. As the assurance procedures performed in a limited assurance engagement are less comprehensive than in a reasonable assurance engagement, the level of assurance obtained is substantially lower. The choice of assurance procedures is subject to the auditor’s own judgement.

Within the scope of our engagement we performed, amongst others, the following procedures:

  • Inquiries of group-level personnel who are responsible for the materiality analysis in order to understand the processes for determining material topics and respective reporting boundaries for METRO AG
  • A risk analysis, including a media research, to identify relevant information on METRO AG’s sustainability performance in the reporting period
  • Evaluation of the design and the implementation of systems and processes for the collection, processing and monitoring of disclosures, including data consolidation, on environmental, employee and social matters, respect for human rights, and combatting corruption and bribery matters
  • Inquiries of group-level personnel who are responsible for determining disclosures on concepts, due diligence processes, results and risks, performing internal control functions and consolidating disclosures
  • Inspection of selected internal and external documents
  • Analytical procedures for the evaluation of data and of the trends of quantitative disclosures as reported at group level by all sites
  • Assessment of local data collection and reporting processes and reliability of reported data via a sampling survey at METRO Deutschland GmbH, METRO Italia Cash and Carry S. P. A. and Makro Cash and Carry Polska S.A. via videoconference
  • Assessment of the overall presentation of the disclosures.

In our opinion, we obtained sufficient and appropriate evidence for reaching a conclusion for the assurance engagement.

Independence and Quality Assurance on the Part of the Auditing Firm

In performing this engagement, we applied the legal provisions and professional pronouncements regarding independence and quality assurance, in particular the Professional Code for German Public Auditors and Chartered Accountants (in Germany) and the quality assurance standard of the German Institute of Public Auditors (Institut der Wirtschaftsprüfer, IDW) regarding quality assurance requirements in audit practice (IDW QS 1).


Based on the procedures performed and the evidence obtained, nothing has come to our attention that causes us to believe that the sustainability information in the “Corporate Responsibility Report 2021/22” of METRO AG, published online at for the period from October 1, 2021 to September 30, 2022, has not been prepared, in all material respects, in accordance with the Reporting Criteria.
